Beware of counterfeit connectors!

Illegal imitations of our MC3 and MC4 connectors keep appearing on the market. On the outside, they are hard to tell from the original, but technical comparisons often reveal serious deficiencies in the quality of counterfeits. The lack of safety-relevant characteristics such as UV resistance and density (IP67) harbours potential risks and may result in damage to or failure of the installation or even fire. For safety reasons, Multi-Contact advises against using any copied products.
Rely on the Original!
